Image forming apparatus, and process cartridge for use in image forming apparatus

A process cartridge for use in an image forming apparatus, the image forming apparatus comprising:

• a main body;
• a latent image support supporting an electrostatic latent image;
• a charging unit charging a surface of the image support;
• a latent image formation unit forming an electrostatic latent image on the image support surface;
• a developing unit developing the electrostatic latent image with toner to form a toner image on the image support;
• a transfer unit transferring the toner image from the image support to a recording medium;
• and
• a recording medium transport unit transporting the recording medium so that the surface of the image support is countered to a surface of the recording medium,
• wherein the process cartridge includes the image support and at least one of the charging unit, the image formation unit, the developing unit, the transfer unit and an image support cleaning unit, which are integrally provided in the process cartridge, and the process cartridge is provided to be removable from the main body,
• wherein the surface of the image support has a coefficient of friction that is in a range of 0.1 to 0.7 according to Euler belt method, and a difference between a rotation speed of the image support and a transport speed of the recording medium is below 1%, and the image support has an outermost surface containing at least a filler and a binder resin.
